DeReAct paper: modular Critic and Context Manager for more reliable ReAct-style agents
The arXiv preprint introduces DeReAct, a modular agent architecture that externalizes two gating policies—a Critic to validate proposed actions and a Context Manager to reconstruct environment-supported state and certify task completion. On GAIA and SWE-bench Verified, DeReAct raises Pass@1 most for weaker "Brain" models (6.5–7.0 points for Qwen3-Coder-480B, 4.2–5.2 points for Claude Sonnet 4.5), with smaller gains as model capability increases; with Claude Opus 4.5 overall Pass@1 is comparable to ReAct but trajectories are more evidence-complete and constraint-satisfying.
